Problems solved by technology

[0003] However, due to the high wear resistance and hardness of the wear-resistant steel plate, the processing of the countersunk hole generally requires a special high-alloy drill bit for the wear-resistant plate to drill the hole first, and then the drill bit meets the requirements of the countersink hole through the milling cutter. Reaming, and the life of the drill bit is not long, resulting in a significant increase in processing costs
[0004] Therefore there is above-mentioned inconvenience and problem in the counterbore processing method of known wear-resistant liner

Embodiment 1

[0029] The counterbore processing method of the wear-resistant liner of the present invention comprises the following steps:

[0030] a. Lofting and blanking

[0031] Lofting is carried out during the blanking stage to ensure the expanded size of the parts;

[0032] b. Hole opening and pressing

[0033] Taking the maximum diameter of the countersunk part as 40mm as an example, open a round hole with a diameter of 50mm at the position of the countersunk hole required by the drawing, and then press the wear-resistant plate to make it reach the required arc;

[0034] c. Machining countersunk hole parts, including the following steps:

[0035] (1) Round steel blanking, the round steel blanking with an outer diameter of 48mm is selected as the blank of the countersunk hole;

[0036] (2) Drill the center hole and drill the center hole on the blank;

[0037] (3) Drill the countersink, and then drill the countersink on the blank with the center hole drilled;

[0038] (4) Mill the...

Abstract

The invention discloses a counterbore processing method for a wear-resisting lining plate. The counterbore processing method for the wear-resisting lining plate is characterized by including steps that a, setting out and blanking; b, tapping and profiling; c, machining a counterbore workpiece; d, welding the counterbore workpiece and drilling an outer bore sleeve. The counterbore processing method for the wear-resisting lining plate has advantages that the manufacturing step design is reasonable, the operation is easy to perform, the wear-resisting lining plate is processed easily and effectively, the mounting size is guaranteed, and the processing cost is greatly lowered.

Description

technical field [0001] The invention relates to a hole processing method, in particular to a counterbore processing method of a wear-resistant liner. Background technique [0002] At present, wear-resistant steel plates are widely used in mining machinery, coal mining machinery, environmental protection machinery, engineering machinery, cement machinery, metallurgical machinery, brick making machinery and other product parts, so that the life of the equipment is longer, and the maintenance shutdown caused by maintenance is reduced. Reduce capital investment. [0003] However, due to the high wear resistance and hardness of the wear-resistant steel plate, the processing of the countersunk hole generally requires a special high-alloy drill bit for wear-resistant plates to drill the hole first, and then use a milling cutter to make the drill bit meet the requirements of the countersink hole. Reaming is carried out, and the life of the drill bit is not long, resulting in a subs...
